2 Claims. (Cl. 248-291) The present invention relates to apparatus for handling carboys,

Acid carboys have always been dangerous to handle. When full of concentrated aqueous acids of high density these thirteen gallon carboys tax thestrength of even two men and render the pouring of such acids by unskilled labor a dangerous operation.

Experience has shown that not only are the cleats conventional carboys positioned at dilferent locations depending on the carboy manufacturer, but also that such cleats are relatively unreliable as supporting means, parsufiiciently great to enable such framemembers 14 to straddle the acid carboy C.

Uprights 18 are provided at the ends of frame mem-f' bers 14. The arms 20 for the drum lift 12 are pivotably secured to the uprights 18. The pivoting of the arms 20 in respect to the uprights 18 is effected by the hydraulic jack 22 which is actuated by the pedal 24, the hydraulic ticularly when the carboy has been used for any length of time. Thus, the acid discharged from such carboys is prone to attack the nails and other securement means joining the cleats to the carboys, resulting in disengagement of the cleats from the carboys upon stress being applied to the cleats. Moreover, the bottom of the carboy is prone to become disengaged due to acid attack.

This invention has as an object the provision of apparatus for handling carboys, which apparatus may be used to safely handle such carboys even though the carboy is in poor condition.

This invention has as another object the provision of apparatus for handling carboys of different outside dimensions, which apparatus can accommodate to carboys of such different outside dimensions.

This invention has as yet another object the provision of apparatus which will enable a single individual to safely manipulate conventional thirteen gallon acid carboys loaded with noxious liquids.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

Referring to the drawings wherein like reference characters refer to like parts:

Figure 1 is a side elevational view of the apparatus for handling carboys of the present invention carried on a conventional one-man drum lift.

Figure 2 is a sectional view showing the locking means in closed disposition.

Figure 3 is a fragmentary view showing the locking means in open disposition.

Figure 4 is a perspective view of the apparatus of the present invention.

The apparatus of the present invention for handling a conventional acid carboy (designated C) comprises the girdle designated as 10. Such girdle is intended for use in a conventional one-man operated drum lift 12.

The drum lift 12 in the illustrated embodiment (no claim to invention is made in the present application for the drum lift) comprises horizontal frame members 14 which are spaced from each other and mounted on casters 16. The distance between the frame members 14 is jack 22 being engaged with a cross-bar connecting the arms 20.

The free end of each of the arms 20 is provided with a' clamp 26. Trunnion 28 of girdle 10 is received withinthe clamp 26 of one of the arms 20, and trunnion 30 of girdle 10 is received in the clamp 26 of the other of arms 20. Each of the clamps 26 is provided with threaded securement means 32 for locking the clamps 26 onto their respective trunnions 28 and 30.

Trunnions 28 and 30 are oppositely positioned and extend outwardly from the strap 34. The strap 34 is generally re'ctangularly shaped and formed of sheet metal or fiat bar. Strap 34 includes the side members 36 and 38, theback member 40 and front members 42 and 44. The trunnion 28 projects outwardly from the middle portion of side member 36 and the trunnion 30 projects outwardly from the middle portion of side member 38.

The back member '40 is provided with three evenly spaced outwardly projecting threaded studs 46, 48, and 50.

The central threaded stud 48 carries the upwardly projecting angle-shaped jaw 52 which includes the straight inwardly directed projection 56. Element 54 is provided with the elliptical slot 58 through which the threaded stud 48 extends. Wing nut 60 carried on threaded stud 48 may be used to selectively engage the element 54 so that the same may be locked in any desired position in respect to back member 40. Y

The threaded studs 46 and 50 carry the downwardly projecting angle-shaped jaws 62 and 64. Each of these jaws includes the straight element 66 whose end portion comprises the inwardly directed projection'68 for supporting the bottom of the carboy C. The elements 66 of angle-shaped jaws 62 and 64 are each provided with elliptical slots 70 for permitting vertical adjustment of the angle-shaped jaws 62 and 64 in respect to the back member 40. Wing nuts 72 and 74 are provided on threaded studs 46 and 50 for locking the angle-shaped jaws 62 and 64 in a predetermined disposition.

Front member 42 is hinged by means of hinge 76 to the front end of side member 36 and front member 44 is hinged by means of hinge 78 to the front end of side member 38.

Front member 42 is provided with the keeper 80 of locking means 82.

Front member 44 includes the locking lever 84 of locking,means 82. Locking lever 84 is threadably secured through upright 86 which is secured intermediate the connecting members 88 of the portion of locking means 82 carried by front member 44. The connecting members 88 are secured to front member 44 by upright 90 which is pivotably joined to both front member 44 and to connecting members 88.

The operation of the girdle 10 of the present invention is as follows: i

The girdle 10 is retained by the drum lift 12 with the projections 68 resting on the ground. Such projections 68 of the jaws 62 and 64 of girdle 10 are slipped under the bottom of the acid carboy C intermediate the cleats which are conventionally secured to the bottom of an acid carboy. The strap 34 embraces the sides of the acid carboy.

The operator then adjusts the wing nuts 72 and 74 so Patented May 24, 196.0.

The locking means 82 is then closed, .in the manner shown in Figures 2 and 3. Thus, the locking lever 84 is engaged with the keeper 80 and then pivoted to effect locking. Since the locking lever 84is threaded, it provides for accommodation to acid carboys of dilferent girths.

Pouring of the noxious liquid contents from the carboy C can be accomplished when the same is mounted on the lift 12 with ease by a single operator. Thus, the trunnions 28 and 30 may be pivoted in respect to their supporting clamps 26 so that the carboy C assumes the desired position, and the arms 20 may be raised or lowered by the hydraulic jack 22.

The girdle 10 of the present invention permits positive securement to acid carboys C even though the same are in poor condition, as in the case of carboys Whose cleats and/or bottom have either separated from the sides of the carboy or are loosely attached to the sides of the carboy.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.

I claim:

1. A girdle for a carboy including a rectangularly shaped girdling member, one side of said girdling member having ends hinged to opposed sides of said girdling member and free ends intermediate its hinged ends, locking means on the free ends of said one side, opposed trunnions projecting outwardly from said opposed sides, three angle-shaped elements extending perpendicularly across and secured to the side of said girdling member opposite the side having hinged ends so as to be selectively movable in respect to said girdling member, and means for securing each of said angle-shaped elements in a predetermnied disposition in respect to said girdling member, two of said angleshaped elements extending below and one element extending above said girdling member, with the offset projection of each of said elements extending inwardly.

2. A girdle for a carboy in accordance with claim 1 in which the angle-shaped element which extends above the girdling member is secured to the center of the side of the girdling member, and the two angle-shaped elements which extend below the girdling member are secured to the side of the girdling member on opposite sides of said upwardly extending element.
